Useful:

• Physical Properties: Anhydrous sodium sulfate is a white crystalline powder; orthorhombic or hexagonal structure; hygroscopic; refractive index 1.468; hardness 2.8 Mohs; density 2.664 g/cm3; melts at 884°C; soluble in water, insoluble in ethanol. The decahydrate consists of colorless monoclinic crystals; refractive index 1.394; hardness 1.8 Mohs; density 1.4 6g/cm3; decomposes at 32°C; soluble in water; insoluble in ethanol.
• Uses: Sodium sulfate decahydrate is used in manufacturing paper pulp by the Kraft Process. Other uses are in manufacturing glass and ultramarine; in dyeing and printing textiles; as a filler in synthetic detergents; and for standardizing dyes. A major use of anhydrous sodium sulfate is as an agent to remove water from organic solvents and their extracts for organic synthesis and instrumental analysis. Sodium sulfate decahydrate is a common laboratory reagent. Also, it is used to prepare other sodium salts. Sodium sulfate decahydrate is used as a laboratory reagent to precipitate protein. It is largely used as filler in powdered home laundry detergents. It facilitates in leveling, reducing negative charges on fibers, thereby allows dye to penetrate evenly. It avoids the corrosion of stainless steel vessels used in dyeing. It is also used as a laxative and effectively replaces the drug paracetamol in the body. Sodium sulfate decahydrate may be used to deepen the color while dyeing cotton fabrics.6
